"The growing number of cloud Additive Manufacturing (AM) services, offered by different providers over the Internet, makes it challenging for consumers to compare these cloud AM services to select a service of their choice. In addition, it is even more challenging for consumers to compare these cloud AM services against their personal preferences. This is because, consumers personal preferences on multiple service attributes such as price, material, accuracy, and schedule, should be considered for cloud AM service selection. The decentralized nature of these cloud AM services coupled by the need to consider consumers personal preferences during cloud AM service selection, requires a system that will serve as a broker between cloud AM services and consumers. But, existing frameworks of cloud manufacturing either do not have brokers between cloud manufacturing service providers and consumers or do not support personalized preference and tradeoff based brokerage. To address these issues, we propose a cloud additive manufacturing framework which consists of a service broker system for cloud AM services that provides consumers with a single point of access to a large number of cloud AM services from many additive manufacturing service providers. This broker system also incorporates the first real application of service selection with fuzzy logic based personalized preferences and tradeoff. We also develop a method to generate fuzzy membership functions for each service attribute. This makes it easy for consumers to specify their fuzzy membership functions. We present an application case study to demonstrate the feasibility of brokerage in cloud AM services and finally evaluate our method in terms of performance"--Abstract, page iii.
